Frequently Asked Questions

Voidcom is a communication platform for gamers and communities. It offers low-latency voice chat, real-time messaging, video and screen sharing, servers with channels, roles, and moderation tools. DMs and voice calls are end-to-end encrypted. Server channels use transport encryption.

Yes. Voidcom is completely free during beta with all features unlocked and no limits. After launch, we'll move to a freemium model — core communication features will always be free. The paid Abyss tier is reserved for bandwidth-heavy extras like HD video, HD screen sharing, and larger file uploads.

Voidcom ships today for Windows 10/11 (x64) and Linux (AppImage, .deb, .rpm, Arch). macOS and iOS are built and running internally — a TestFlight + App Store distribution loop is the last step before they enter public beta. Android is close behind. A web client remains on the longer-term roadmap. Check the download page for the latest availability.

Voidcom is a native app — not a browser in disguise — which means lower memory usage and lower latency. DMs and voice are end-to-end encrypted with post-quantum cryptography. We use QUIC for low-latency voice transport, and the entire server is built in Rust for performance. See the full comparison.

Download Voidcom from the download page, install it, and launch the app. You'll see a registration screen where you can create an account with a username, email, and password.

Click the "+" button in the server sidebar. Give your server a name and optional description. You can make it public (discoverable) or private (invite-only). Channels are created automatically, and you can add more as needed.

Inside your server, use the invite system to generate a shareable invite code. You can set usage limits and expiry times. Send the code to your friends — they can use it to join your server.

Click on any voice channel in the server sidebar. You'll automatically connect and can start talking. Use the controls at the bottom to mute, deafen, or adjust your settings.

Voidcom offers 5 quality presets: Esports (48 kbps, 5ms frames — fastest reactions), Low Latency (48 kbps, 10ms frames), Normal (64 kbps, 20ms frames — default), High Quality (128 kbps, 20ms frames), and Maximum (256 kbps, 20ms frames — best for music).

Open your voice settings and switch the input mode from "Voice Activity" to "Push-to-Talk". Then assign a keybind. Your microphone will only transmit when you hold that key.

Video and screen sharing is in alpha. Capture, hardware-accelerated H.264 encoding (VideoToolbox on Apple platforms, NVENC/AMF/QSV elsewhere), decoding, and SFU forwarding all work end-to-end. You can manually subscribe to specific streams in a call and pop them out into their own OS window. Quality presets and reliability are still being tuned. See the roadmap for live status.

End-to-end encryption (E2E) means your data is encrypted on your device before being sent, and only decrypted on the recipient's device. In Voidcom, DMs and voice calls are E2E encrypted with a post-quantum hybrid key exchange (X25519 + ML-KEM-768) — the server stores zero plaintext and can't listen to your conversations. That hybrid is now performed via AWS LC's HPKE implementation of the ML_KEM_768_X25519 (XWing) ciphersuite, so DM key wrap and voice keying share one audited library and one post-quantum hybrid construction. Voice is keyed by MLS 1.0 (RFC 9420), the same protocol family as Discord DAVE, with per-sender signature keys and forward secrecy on leave. Voice rooms above 99 participants are a separate "Stage" channel type that is server-mediated rather than E2E (matches the posture Discord takes for its Stage channels). Server text channels use transport encryption so that owners can moderate their communities.

Your password never leaves your device in a recoverable form. Login uses SRP6a (Secure Remote Password), so the server can verify you without ever receiving your password or anything reversible to it. The same password also derives a key-encryption-key locally that unlocks your end-to-end encrypted keys — the server stores only the wrapped blob. If you forget your password, a BIP-39 recovery phrase generated at signup restores access; if both are lost, your encrypted data cannot be recovered, and we cannot help with that.

We collect the minimum data needed to operate the service (account info, server memberships). We do not mine your messages, sell your data, or show ads. Our website uses self-hosted, cookie-free analytics that doesn't track individual users. See our privacy policy.

Windows 10/11 (x64), Linux x86_64 (glibc 2.31+), or macOS (Apple Silicon or Intel). 4 GB RAM minimum, an audio input/output device, and an internet connection. For hardware-accelerated video/screen sharing, an H.264-capable GPU (NVIDIA, AMD, Intel, or Apple Silicon via VideoToolbox). Mobile (iOS/Android) system requirements will be published when public beta opens.

Most networks work out of the box. Try restarting the app and checking your internet connection. If you're behind a strict firewall or corporate network, it may block Voidcom's traffic — try a different network. If you're still having issues, reach out to us.

We don't have a fixed launch date. We're focused on getting the product right. Follow our blog and roadmap for updates on progress.

We intend to carry over all user data from beta to launch. However, during beta there may be rare cases where a database migration requires a reset. We'll always give advance notice if that happens.

You can report bugs by reaching out to us at team@voidcom.app with a description of the issue, steps to reproduce, and any relevant screenshots or logs.
